FitFace Studio: reconstructing Galaxy Fit3 watch-face editing and delivery

FitFace Studio reconstructs Galaxy Fit3 watch-face editing and Bluetooth delivery in an Android app. It parses and rewrites the face's binary container, validates its size and content, and documents the RFCOMM transfer sequence used to send it to an SM-R390 watch. The editor supports backgrounds, widgets and styles while retaining projects on the phone.
